Details

Edelbrock Part # 7520 Air-Gap Dual-Quad-O intake manifold is designed for street 396-502 c.i.d. Chevy V8's with 1975 & earlier oval port heads. This intake stands 7/8" taller than the low-profile C-66-O dual-quad intake and offer performance improvements in the 1500-6500 rpm range. The large runners feature our unique Air-Gap design that separates the runners from the hot engine valley for a cooler, denser charge.
